The Central Meteorological Observatory issued the first cold wave warning in the second half of the year, and strong cold air will repel large-scale high temperature weather in the south.

Cctv newsAccording to the Central Meteorological Observatory, it is estimated that from October 2 to 6, strong cold air will affect most parts of central and eastern China, bringing strong winds and strong cooling weather. The Central Meteorological Observatory issued a cold wave blue warning on the morning of the 2 nd, which is also the first cold wave warning in the second half of this year.

Because the early temperature in most parts of the central and eastern regions is obviously higher than normal, and there has been a large range of high temperature weather in the south since September 30 and will continue until the 4 th, the highest temperature in many stations has exceeded the historical extreme value in the same period; Affected by this strong cold air, several provinces will experience severe cooling. The specific weather forecast is as follows:

Cooling and minimum temperature forecastIt is estimated that the temperature will generally drop by 8 ~ 12℃ in most parts of central and eastern China from 14: 00 on October 2 to 20: 00 on October 6, and the temperature will drop by 12 ~ 16℃ in central and eastern Inner Mongolia, northeast China, most of Shaanxi, southwestern Shanxi, Henan, southern Shandong, Jiangsu, Anhui, Hubei, northern Hunan, northwestern Jiangxi and northern Zhejiang, and in central Inner Mongolia, eastern Heilongjiang, eastern Jilin and other places.

On the morning of the 6th to 7th, the lowest temperature 0℃ line will be located in the north of Shanxi, the north of Hebei and the north of Liaoning, and the lowest temperature 10℃ line will be located in the northeast of Sichuan, the north of Hubei, the south of Henan and the south of Shandong. During this period, the daily maximum temperature in capital cities such as Nanjing, Hefei and Wuhan will drop from 37-39℃ on the 2nd to 13-15℃, and the minimum temperature will drop from 26-28℃ to 11-13℃.

Meteorologists reminded that the strong cold air process has a wide range of influences and severe cooling, especially in some parts of the south, where the temperature first increased and then plummeted. The public should pay attention to the temperature changes and add clothes in time to guard against physical discomfort caused by alternating cold and hot. In addition, it is necessary to do a good job in wind prevention and reinforcement of simple facilities and high-altitude structures.
